BOBBIN SUPPORT FOR HAND KNITTING MACHINES.

Application filed July 24, 1924. Serial No. 727,993.

' To all whom it may concern:

nary bobbin, when the thread is low .the

thread catches on the topof the bobbin and breaks, and when the bobbinis full the thread often catches on the Weight or on the thread guideand thus causes the thread to break and thus let the sock or stockincome off of the needles.

One of the objects of the present inven tion is to do away with thischanceof breakingthe thread by supporting a thread spool at sucha'distance from the knitting machine that the thread will not catcheither upon the upper end of the original bobbin support or upon thethread guide or weight.

A further object is to provide a spool support which is so 'constructed"that it may be attached by simply placin it upon the usual stand, thesupport under t ese circumstances supporting the knitter or machine, andbeing so constructed that when in place it will not move around or comeoff the stand, the support being so constructed, however, that it"can bemoved around with the machine without trouble.

' A still further object is to provide an attachment for use with aknitting machine stand which will. permit of the use a thread spool aswell as the usual bobbin on the machine which :is used when reinforcingan article.

Another object is to provide a spool holder which will project out farenough and be siifiiciently high as to make it easy to use the threadfrom the spool when using a reinforcing thread and thus have boththreads very close to hand. i

My invention is illustrated in the accompanying drawing, wherein Figure1 is a perspective View of a circular knitting machine and stand with myattachment applied thereto;

Figure 2 is a top plan view of the attachment; a

Figure 3 is a top plan view of the ordinary knitting machine stand; I

Figure 4 is a section on the line 4c-t of Figure 3; i

Referring to these drawings, it will be seen that I have illustrated astand upon which a circular hand knitting machine is mounted. This standhas a substantially circular fiat rim 10 with a raised. edge 11extending partly around it. This stand is supported by three legs 12;connected at their lower ends by braces 13. The raised edge 11 of member,10 is interrupted at the front of the st'and,as at 14, and the rim iscut inward or recessed, as at 15. These raised edges 11 or flangesextend only partly around .the rim 10. Projecting rearward from the rim10 is a rearwardly extending, U-shaped portion 16; On eachside of thisU-shaped portion there are relatively shallow needle trays 17, The rearwall 18 of the U-shaped portion 16 is relatively fiat and relativelywide.

So far I have described the ordinary knittingmachine stand such as iscommonly used. The knitting machine ordinarily used with such a stand asthis may be of any ordinary or conventional construction butis shown ashaving a circular body 19 which is disposed over the central opening inthe supporting rim 10 and as resting upon this rim so that; the stockingor sock or other article being; knitted passes downward through thecenterof the knitting machine and down through the central opening inthe rim 10.

The knitting machineis provided with a downwardly and rearwardlyprojecting clamping ear 20 and two outwardly projecting divergent cars21 disposed on each side of the clamping ear. The clamping car 20 isprovided with a set screw whereby thedevice may engage with the stand orwith the table. Mounted upon one of the ears 20 is a spindle 22 adaptedto carry the usual cone-shaped bobbin. The machine is also provided withthe usual guide rod 23 upon which the weight 24 is mounted and with thethread guide 25 having eyes 26. Vhen a hand knitting machine ofthischaracter is used, the thread coming from the bobbin 22 on the bobbinsupport 22 is very liable'to catch on the top of the bobbin beoause thebobbin 22 is disposed too closely to the guide rod and it leansoutwardly and the thread passing through the eyes in the guide rod 25and coming off ofv therefore, the thread will not catch on the of theusual bobbin 2:2. scribed the ordinary knitting machine stand top of thespool, and that the thread shall come at such an angle as to prevent anypossibility of the thread catching on the top So far I have do such asquite commonly used and an ordinary type of circular automatic hand opcrated knitter, it being understood that the knitting machlne and thestand are neither of them parts of my invention but that they arestandard articles and that any suitable stand and any type of knittingmachine of the general character illustrated are 1Il-- tended to besignified by the drawings.

My improved spool holder comprises a sheet metal plate 28 which is cutout in the center so to conform, generally speakingto the shape of therim 10 and rest thereon, the plate being further formed to provide arearwardly projecting flat web 29 having somewhat divergent side edges.The central openingis extended into this web 29,, as at 30. The frameformed by cutting out the plate 28 is so formed as to provide arelatively narrow portion 31 which coincides with the relatively narrowportion of the rim 10 behind the recess 15, this narrow portion 31resting upon this narrow portion oi the rim 10.

The rear portion of the rim 28 is formed with. radially projectingshouldersSQ which engage behind the rear ends of the flanges 11, thuspreventing the plate or rim 28 from oscillating upon the rim 10. The.rear end of the. web 29, which,'as before stated, is made of sheetmetal, is relatively wide and preferably beaded, and a relatively heavybail-like member 33 is supported within this bead having upwardlyextending arms whose extremities are inwardly turned and adapted to bedisposed within openings formed in the extremities of the spoolspindle34;.

In use, this improved spool holder'is disposed upon the stand, the slotor extension 30 of the central opening-being coincident with the openingin the U-shaped member 16 ot. the stand. The knitting machine is thendisposed upon the rim 28. The medially disposed ear 19 extends downwardthrough or is received by the o 'ienings 30 and 16. A set screw on theextremity ol this ear engages the flat portion or wall attheend of theopening-16 in the usual manner. The ears 20 extend over the laterallydisposed flat walls of the opening 16 and, therefore, over the portionof the web 29 on each, side of the. opening 30. The

thread is wound upon the spool 31 in an obvious manner.

Preferably this device is made of steel about thick,-the spool'beingabout 3" in diameter and about from S to 6 long. My attachment supportsthe spool spaced from the guide rod and inasmuch as the spool is notcone-shaped,the thread will not catch on the apex of the cone The threadcomes from such an angle as to preventthis. The attachment.- rests uponthe stand and the machine seats on the attachment and on the stand withthe clamp disposed downward through the opening and clamping to bothdevices. I

VVhile- I have illustrated this attachment as applied to a stand andwhile this attachment is particularly adapted for a stand, I wish itunderstood that it may be applied to a table in exactly the same mannerand that here again it will support the spool in such spaced relation aswill preventthe thread from the spool catching over the usual bobbinsupport or on the thread guide or weight.

I claini: v v

1. As an article of nianufacture,an auxiliary spool support for handoperated knit ting machines comprising a sheet metal member cut out atone end to form a suhe stantially annular portion adapted 'to bedisposed beneath the knitting machine and engaged therewith againstrotary movement,

the annular member having a radial outstanding web carrylng an auxiliaryspool at its outer end, the opening of the annular member being extendedout-Ward into said web whereby to accommodate the usual clamps on aknitting machine.

2. As an article of manufacture, an auxiliary spool support of sheetmetal formed to provide a somewhat narrow annular portion, the front; ofthe annular portion be ing recessed, the rear of the annular portiononeach side being widened to provide two outstanding shoulders wherebyto receive and accommodate the flanges of the usual knitting machine suport, thesheet metal being radially extent ed to form a web, the outerend .of the web having upstanding arms to detach ably support an iliaryspool.

3. As an article of manufacture, an auxiliary spool support ofsheetmetal formed to provide a portion adapted to be disposed beneath acircular knitting machine and a' portion extending rearward thereof, thefirst named portion having an opening, the rear of the opening beingrearwardly extended,

aux-

the front portion of the opening having a transversely extendingstraight edge at an inclination to the longitudinal axis of the supportand there being a recess extending inward from the periphery of thefirst named portion of the support toward said straight edge, theperiphery of the support laterally of said recess being concentricallycurved and formed to provide oppositely 10 disposed. outwardlyprojecting shoulders whereby to receive and accommodate the flanges ofthe usual knitting machine support and rest thereon, the rearWa-rdlyextending portion of the support being in the form of a Web havingupstanding arms, and a spool rotatably mounted upon said arms.

In testimony whereof I hereunto aflix my signature.
